About this mod Author’s original text

SandevistanFX

Turns BONELAB's slow-motion ability into a Sandevistan, inspired by Cyberpunk: Edgerunners.

Requires Quicksilver by Lakatrazz, so you move at full speed while the rest of the world crawls.

Features

  • Neon green world. The moment slow-mo kicks in, the world flashes and gets a neon green color grade.
  • You keep your normal colors. Your body, the weapons and items in your hands, and everything in your holsters stay their real colors while the world turns green.
  • Rainbow afterimages. Copies of your avatar and your gear trail behind you as you move. Their color drifts slowly through the rainbow, up to 50 can be on screen at once, and each one stays solid until it disappears instantly. No fading.
  • Gone the moment you stop. Turn slow-mo off and every afterimage vanishes at once, and the green grade fades out.

Installation

With a mod manager (recommended): install through r2modman or the Mod Manager. MelonLoader, BoneLib and Quicksilver are installed automatically.

Manually:

  • Install MelonLoader, BoneLib and Quicksilver.
  • Put SandevistanFX.dll from the Mods folder of this download into BONELAB\Mods.
  • Start the game and use slow-mo.

Settings

Open BoneMenu → Sandevistan FX in game. Turn on Preview (force on) to see the effect without slow-mo while you adjust it.

All settings are also in BONELAB\UserData\MelonPreferences.cfg under [SandevistanFX].

| Setting | Default | What it does |

|---|---|---|

| GradeColor | #3DFF73 | Color of the world grade (hex) |

| GradeStrength | 0.7 | How strongly the world is tinted |

| ActivationFlash | 0.5 | Brightness of the flash when slow-mo starts |

| FadeOutTime | 0.15 | Seconds for the green to fade out (0 = instant) |

| KeepPlayerColors | true | Keep you and your gear in normal colors |

| AfterimageInterval | 0.06 | Seconds between afterimages |

| AfterimageLifetime | 3 | Seconds each afterimage stays |

| AfterimageOpacity | 0.5 | How see-through afterimages are |

| AfterimageHueSpeed | 0.2 | How fast the rainbow color changes |

| AfterimageMaxCount | 50 | Most afterimages on screen at once |

| AfterimageIncludeItems | true | Include held and holstered items in afterimages |

| AfterimageAdditive | false | Glowing afterimages instead of solid see-through ones |

| TriggerOnAnyTimeSlowdown | false | Also trigger when time is slowed by other mods |

Troubleshooting

  • No green grade or afterimages: turn on Use Fallback Shader in BoneMenu. The grade becomes a green wash instead of a color filter.
  • An afterimage sits on top of your body when you activate: raise AfterimageRevealDistance to 0.12 so afterimages wait until you move away before appearing.
  • Moving in slow motion with the rest of the world: Quicksilver is missing or turned off. Install it, and check that BoneMenu → Quicksilver → Mod Toggle is on.
  • For anything else, check BONELAB\MelonLoader\Latest.log for lines starting with [SandevistanFX].

Known limits

  • The view through scopes stays untinted.
  • While the grade is up, glass or particles in front of your hands won't cover them.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
